Explain DC Voltage:

A steady voltage source is known as a DC Voltage with a voltage that changes occasionally with time is called an AC voltage. Voltage is measured in volts, with one volt being characterized as the electrical weight required to drive an electrical current of one ampere through a resistance of one Ohm. Voltages are by and large communicated in Volts with prefixes used to indicate sub-products of the voltage, for example, microvolts ( μV = 10-6 V ), millivolts ( mV = 10-3 V ) or kilovolts ( kV = 103 V ). Voltage can be either positive or negative.

Batteries or power supplies are for the most part used to deliver an unfaltering D.C. (coordinate current) voltage source, for example, 5v, 12v, 24v and so on in electronic circuits and frameworks. While A.C. (rotating current) voltage sources are accessible for local house and mechanical power and lighting and in addition control transmission. The mains voltage supply in the United Kingdom is right now 230 volts a.c. what's more, 110 volts a.c. in the USA.

General electronic circuits work on low voltage DC battery supplies of in the vicinity of 1.5V and 24V dc The circuit image for a steady voltage source typically given as a battery image with a positive, + and negative, – sign demonstrating the course of the extremity. The circuit image for a rotating voltage source is a hover with a sine wave inside
